As of 7/16/17, I have three HD Homerun Tuners, Each tuner has a dedicated antennae pointed in the optimal direction. I have limited unique channels to each tuner with NO OVERLAP in the Plex DVR Setup Software. IE> Tuner A has Channels 2 & 5 only. Tuner B has Channel 11 only. Tuner C has Channel 36 only.
Now if you tell it to record channel 2 only --> It will record properly off of Tuner A. However, If you tell it to record Channel 11 or 36 by themselves… THEY TOO record on Tuner A!! I have also learned that if multiple channels are told to record they activate the Tuners in sequential order Only one channel = Tuner A 1 is used. Two Channels Tuner A 1 and Tuner A 2 are used (HD homerun has two tuners in a single unit) Three Channels to record - Tuner A1/A2 and Tuner B1 … Four Channels results in Tuner A1/A2 and Tuner B1/B2 being activated and so on… IN OTHERWORDS. It is NOT selecting the tuner utilized for recording with any priority/respect to actual channels actively identified in the DVR setup for each tuner. (You can specify to disregard all channels on Tuner A except 2 & 5… But if you tell it to record Channel 11 It will record off tuner A because it is the first in the sequence of Tuners. ) To the Plex Engineers working the DVR Beta… I ask “I am correct???”
I have seen this problem as my 3rd tuner only has local channels. I have found a way to fix it and since it only comes up rarely for me it has worked. Although for you I think it will be a lot of work. I make sure to lower the priority all the things I want to tune to after tuner 2. This isn’t a big deal for me because Tuner 1 and Tuner 2 receive the channels. I would like to turn off the channels for tuner 1 and tuner 2 so there could be some splitting of tuners although the last time I suggested something similar, I was told it wasn’t a priority.
